I recommend a contract type relationship for a couple weeks or month, something where you can actually see their work, how they work and if they are a good fit for you. Just arrange it so you own all IP if it doesn't work out. As far as finding co-founders, you can hit up various Hackers & Founders meetups. If you're the technical type then finding user groups or whatever can be a good place too. Startup Weekends can also be a good place to look, but don't be super pushy about it (or you'll just be like everyone else there). Also, this is a great article on the topic: http://venturehacks.com/articles/pick-cofounder http://venturehacks.com/articles/pick-cofounder
